Application filed arch tl,

To all whom it may concern Be it known that l, Emmen Minnen vonMARCHTHAL, a subject oi' the Emperor of Austria-Hungary, and residing.,vat Vienna, Austria-Hungary, have invented certain new and usefulImprovements in Appunto tus for Closing an Electric Circuit ut lredetermined Positions of :i Collemor, ot which the following is f1specification.

My invention relates to apparatus for closing an electric circuit at.predetermined positions of a collector.

Devices are known for closing: u circuit ut a predetermined selectiveposition of o shaft, e. g. for telegrzrphic apparatus, uuic matictypewriting, type-setting', typeist. ing and other machines. ileltknoivnde vices of this tjvpe comprise u number ot switches and a collectordriven h v the slnrt'l. The segments of the collector', the brushesslidingr on it and the-switches :ire so con- 4nected With one anothertliut when the switches are 1n u predetermined position collector musthe in a predetermined posi tion under the brushes in order to close thecircuit. i

A primary object oimy inif'ention is to provide improved apparatus ofthis type. To this end, I make the number of switches as small aspossible, the collector and the connecting` lines as simple as possible,und the positions of the shaft in which o oircuit can be closed asnumerous as possihle. obtain these advantages hy arranging' that theconnectingr lines from the switches do not lead, as in well-knownapparatus, lo the brushes of the collector', hut to the segmentsthereof, the collector heine' stationary :ind the brushes rotating'.
